GUMMING AND PASTING MACHINE Filed Aug. 31, 1949 6 Sheets-Sheet 6 Patented June 10, 1952 GUMMING AND PASTIN G MACHINE Charles A. Surridge, Herne Hill, London, England, assignor to The Sulby Engineering Development Company Limited, London, England v Application August 31, 1949, Serial No. 113,258 In Great Britain September 3, 1948 10 Claims. (01. 11-1) The machine forming the subject of the present invention has been designed to gum or paste together along one edge, sheets of paper or similar substances and is particularly suitable for use in the bookbinding trade as an end papering or plating machine, the gumming or pasting of each book section and end paper or plate and the pressing together of the gummed or pasted parts being performed automatically.

A gumming and pasting machine according to the present invention comprises a gumming wheel, a reservoir or tank for the adhesive and for the delivery of adhesive to the opposite faces of the wheel adjacent its periphery, guiding means for the papers or the like into andout of contact with the gummed surfaces of said wheel so that the opposite edges of the papers are coated with adhesive, means for feeding said papers automatically through the machine past the wheel, positioning means for ensuring correct relative position of said papers during the gumming operation and means for pressing the adhesive coated edges of the papers together.

In order that the invention may be clearly understood and readily carried into effect the invention is hereinafter described with reference to the accompanying drawings wherein:

Figure 1 is a perspective view of a gumming or pasting machine according to the present invention;

Figure 2 is a plan view with the cover removed;

Figure 6 is a section on the line 6-6 in Figure 2 also drawn to an enlarged scale;

Figure 7 is an inverted plan view of the machine drawn to an enlarged scale;

Figure 8 is a front elevation also enlarged scale;

Figures 9 and 10 are respectively gumming wheel and gum reservoir;

Figures 11 and 12 are detail views illustrating more clearly the machines operation.

The invention will be hereinafter described as applied to a machine primarily intended for end papering or plating book sections, the machine comprising a base I supported on legs 2- and fitted with a removable cover or cowling 3. The general arrangement of the machine is clearly illustrated in Figure 1 and in use the operator stands at the right hand end of the machine and picks up from feed trays 4 and 5 a book section and end drawn to an views of the paper or plate and places them side by side in the machine. Trays 4 and 5 carry each a pile of book sections and end papers or plates, the question as to whether the left hand or right hand tray contains book sections being determined by whether the end papers are to be applied to the front or back of the book. Two such book sectionsand end papers are indicated by reference numerals 6 and I in the process of being placed side by side in the machine.

It will be appreciated that the machine is entirely automatic in operation and includes not only means for feeding a book section and end paper or plate through a machine and delivering these two components firmly secured together on to an output tray 8, but also includes means for correctly positioning the end paper or plate with respect to the book section prior to these two components being gummed along one edge and pressed firmly together when in a gummed condition.

To facilitate the introduction of a book section and end paper or plate hereinafter referred to as an end paper for convenience of description, the machine includes deflector plates 9 arranged on opposite sides of an inlet opening l0 and a central fixed partition I l. The arrangement is such that the opening ID in conjunction withthe deflector plates 9 form a feed hopper or virtually two feed hoppers on opposite sides of the central fixed partition II, the one part of the hopper, for example, on the left hand side being used to receive a book section and that on the right an end paper, the partition I] serving to maintain the components in spaced relationship. To facilitate the introduction of the book section and end paper the cover 3 of the machine is recessed as at l2 on. opposite sides of the partiion.

As it is necessary to accurately position the end papers with respect to the book sections, i. e., to ensure that the two components are aligned head to head, the machine includesan endless belt type of feed 13, see particularly Figures 2, 11 and 12, the feed l3 being in the form of a unidirectionally driven endles belt passing around pulleys l4 arranged at opposite ends and driven by suitable means hereinafter described. The endless belt is fitted with a laterally projecting pin I5 which as a result of linear movement of the belt is adapted to .come into engagement with the head of the book section and end paper and feed these two components forwardly into the machine. The operation of this feeding device is clearly shown in Figure 11 which defines a book section and end paper placed side by side in the hopper, but separated by means of partition H. In Figure 11 the pin P is in proces of moving along into the position shown in Figure 12 in which it has made contact with the head of the book section and end paper to move both components forwardly into the machine. The lower edges of the book section and end paper engage longitudinally arranged guides Hi which guides include a central shallow division plate Ilia extending to the periphery of the gum ming wheel for the purpose of ensuring passage of book section and end paper one on either side of the gumming wheel. The endless reed belt may be adjusted from time totime by means of a tensioning screw 11 shown in Figure 2.

The accurately positioned book section and end paper is fed forwardly in spaced relationship and in alignment between the two halves of an endless belt conveyor, the belts being indicated by reference numeral 18 and passing around pulleys 19, the two conveyor belts being drivenat a uniform speed, but in opposite directions to pass the book section and end paper towards the output end of the machine. On thebook section and end paper coming into contact with the two belts of the conveyor they are brought together and finally passed on opposite sides of a guinined wheel nereinaitertobe described. Suitable means are provided for tensioning the two conveyor belts such, as for example,- tension rollers 23 which I engage. the outside walls of the two belts. Two

of these. pulleys l9 havegear wheels 2! associated therewith'which gear wheels are in meshing engagementtd nsureuniform movement of the belts and prevent any possibility of the book section and end paper being creased during its passage through the conveyor.

A fixed conveyor p'late22 is arranged inside the one belt over which plate that belt runs, whilst a second conveyor plate 23 is associated with the other conveyor belt and is urged into contactfthere'with by means of springs 24 so that the belts resiliently grip the book section and endpaper and (not only maintain aligmnent of these componentsprior to them coming into contact withthe gumming wheel, but also press the components together when in a g'um'med condition to ensure the components being firmly stuck together. In addition finger springs 62 are preferably provided which engage the back section or end pa er direct over that part of the section or end paper which has been gummed for the purpose of additionally ensuring a good stick.

After passing the gumming wheel the book section and endpaper continues through the machine and finally engages a delivery guide 25 which is clearly illustrated in Figures 1 and 2, the delivery guide being in the form of a vertically arranged plate carrying a delivery. runner 26 which is adjustably mounted in a slot 2! and serves to deflect the book section and its associated end paper into the output delivery tray 8.

Referring now particularly to Figures 5, 9 and 10 which illustrate in detail the construction of the gumming wheel and its associated reservoir or tank for containing the adhesive, the gumming wheel 28 takes the form of a comparativelythin disc-like component which is tapered towards its periphery and is detachably mounted upon a supporting shaft 29 running in hearings in a journal 30 which in turn has a pin and slot connection 31 with a cover plate 32 for a bath 33 which is supplied with adhesive from an adhesive containing reservoir or tank 34. The tank is fitted at its upper end with a removable plug 35 for filling purposes and has an outlet opening 36 at its lower end in connection with a pipe 31 leading to the bath 33, the opening 36 being closable by means of an axially slidable valve 38 which can be slidden by means of grasping the knob 39 into and out ofv the positionshown in Figure 5 so that the opening 35 is either covered or uncovered, the supply of adhesive from the reservoir to the bath 33 being thereby controlled. Shaft 29 is fitted with a pulley 40 which is driven through the medium of a belt drive.

The driving mechanism for the gumming wheel, endless belt. feed and endless belt conveyor is shown clearly in Figure '1, the various beltsbeing situated below the under surface of the base E, Figure '7 representing an inverted plan view of the machine. The drive includes an electric'motor 4!, the output shaft of which carries a pulley over whichpasses a belt 42 which in turn passes around pulley 43' on which is associated a similar pulley 44 which in turn carries a second belt 45 passingaround pulley '46 onwhich isassociated a similar pulley 41 driving a belt 48 which in turn passes around a pulley 49 associated with one of the conveyor pulleys [9. The driving shaft53 of pulleys46 and 41mm draw ing connection withone of pulleys 14 associated with the endless beltfe'e'd; Pulley ashes a further pulley associated with it of-sr'nallersize over which passes a belt 51 "which inturn passes over a jockey pulley 52 on which is associated a further jockey pulley 53over which runs a further belt 54 which finally passes around pulley 40 associated withthe gumming wheel. In this way the whole of the moving parts of the machine'are operated by means of'a single. drivingmotor:

A scraper 55 is associated with the: gu'mrnin wheel; 28 for the purpose of removing excess adhesive from the periphery of the wheel, the scraper serving to meter the quantity of gum which is carried up by the wheel from the bath 33. Lateral adjustment of the wheel to ensure correct entry of the periphery of the wheel between a book section and endpaper is effected by adjustment of th'escrews 55. Vertical adjust ment of the guinining wheel and the reservoir andthe tankiseifected by means of'a knurled adjusting knob 51 which is associated" with the screw threaded extremity of a downwardly tiepending pin 5szsecui'ed to the base i, the reservoir being slidaole on this pin and a diametri- Cally opposite pin 59 To provide an additional adjustment between thetwo conveyor elements, an adjusting device such as is shown in Figure 5v may be provided, thisadjusting device taking the form of a knurled adjusting knob 69 which when operated varies the resilient pressure "of a coiled a spring: GI acting. on the conveyor plate 23 near the input end of the conveyor.

It will bea-ppreciated from, the-foregoing description of the inventiontliat the book section and end paper on reaohingthe input "end-of '.the conveyor I8 will. pass on opposite sides toLthe pe riphery of. the.- guminiiig wheel 28 and. thegin'nming wheel will thus apply adhesive to the oppo site edges-of theboor section and .end paper in the manner Shown in Figure 5. The width over which adhesive is applied is adjustable by varying the efiectiveheig htof thegu'mming' wheel and after passingthe gum'ming whe'el, the two parts of the conveyor l8 .will firmly press the book section and end paper together along the gummed edges to ensure the components being.

firmly stuck together.

To facilitate entry of the lower edges of the book section and end paper into the longitudinally arranged guides I 6, the fixed partition H is of tapering form in cross section.

The reservoir or tank for the adhesive operates on the barometric principle, the tank being closed at its upper end when the machine is in use and consequently a uniform depth of adhesive is maintained in the bath 33.

To ensure that the pin l5 does not foul the book section and end paper as these components enter the conveyor, the belts of the conveyor are arranged to move faster linearly than the feed belt carrying the pin IS, the pin being thus left behind as the book section and end paper enters the conveyor.

Furthermore, it will be appreciated that by providing a sealed tank or reservoir for the adhesive, skinning of the gum or paste will be prevented, only that quantity in immediate use in the bath being open to the air. In addition the means provided for controlling the level of the gum or paste in the bath hereinbefore described ensures that the quantity of adhesive carried upward by the gumming wheel is constant in quantity and thus ensures uniformity of the gummed or pasted book sections and end papers or plates.
